I feel like maybe around 2012 the whole concept of eras died.
Like I can clearly visualize items/people/media from the 60s/70s/80s/90s/00’s, but everything is homogenized now and there’s really no “style of the time” either. I think everything from 2013+ will just be remembered as a malaise era, if anything. Maybe the style of the 2050’s will be post cyberpunk apocalyptic? I have no idea.
In the age of broadcast media, that is of TV, newspaper, etc., there is a common perspective and culture being set. Now we’re in the “feed” age. There is greater variety and speed.
